UNITED STATES L. S. HOYT AND E. G. HOYT, OF CROTON FALLS, NEW YORK.

IIVIPROVED SCREW-WRENCH AND HAMMER.

Specification forming part of Letters Patent No. 55,107, dated May 29,1866.

To all whom it may concern:

Be it known that we, L. S. HOY'I and E. G. HOY'I, ot' Groton Falls,Westchester county, and State of New York, have invented a new andImproved Screw-Wrench and Hammer Combined; and we do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had tothe accompanying drawings, forming part of thisspecification, in which- Figure 1 represents a front elevation ot thisinvention. Fig. 2 is a side elevation of the same.

Similar letters ot reference indicate like parts.

Thisinvention consists in the arran gement of' a stationary and of ahinged adj ustabe springjaw on one end of a shank or handle, to theother end ot' which a hammer is rigidly attached in such a mannerthatatool is obtained which serves the double purpose of a hammer and ofa screwwrench, which can be made cheap, and which is ot' greatconvenience for farmers and for the public in general.

A represents a shank or handle, made of malleable iron or other suitablematerial; From one end of this handle projects the stationary jaw B,while its other end is rigidly connected to or cast solid with thehammer G.

rlhe stationary jaw B connects by a pivot, a, with the adjustable jaw D,and a screwbolt, b, serves to close up the two jaws and to accommodatethe same to the screw or nut to be turned.

A spring, c, interposed between the two jaws B and D, has a tendency toopen the adjustable jaw as far as the screw-bolt permits, so that byturning said bolt or the nut which may be 'attached to it the jawDpadjusts itself in either direction.

By these means a very convenient wrench is obtained, which can be usedwith advantage on carriages, wagons, or vehicles of any description, orfor other work, and at the same the hammer C renders the whole implementvery convenient and complete.

By casting the hammer and wrench all in one piece (with the exception ofthe adjustable jaw) a very cheap and durable tool is obtained, and notime is 10st in limiting up the hammer or the wrench separate, bothbeing combined in one; and, furthermore, in using our wrench the nut o rbolt can be clasped with the end of the jaws, and the hammer can be usedas a handle, rendering the whole implement very convenient.

What we claim as new, and desire to secure by Letters Patent, is-

The implement herein described, having at one end of its shank A ahammer, C, and at y its other end a stationary jaw, B, in combina' tionwith the adjustable spring-jaw D, as a new article of manufacture.
